  the 
  antennae 
  bearing 
  all 
  over 
  

   except 
  in 
  the 
  middle, 
  where 
  there 
  is 
  a 
  smooth 
  space, 
  

   moderately 
  large 
  punctures 
  ; 
  the

  and 
  vertex 
  very 
  

   smooth 
  and

  ; 
  the 
  median 
  segment 
  

   sparsely 
  covered 
  with 
  long 
  black 
  hairs 
  ; 
  on 
  its 
  side 
  is 
  

   a 
  deep 
  wide 
  furrow, 
  which 
  does 
  not 
  reach 
  the 
  base. 
  

   Wings 
  uniformly 
  deep 
  smok}-, 
  but 
  with 
  a

   tinge. 
  The 
  fore 
  legs 
  entirely

   The 
  petiole 
  above 
  is 
  smooth 
  and 
  shining, 
  except 
  the 
  

   apex 
  in 
  the 
  middle, 
  where 
  it 
  is 
  a 
  little 
  rough 
  ; 
  the 
  

   middle 
  part 
  bounded 
  by 
  the 
  keels 
  is 
  almost 
  transverse, 
  

   and 
  has 
  behind 
  it 
  a 
  small 
  space 
  bearing 
  some 
  minute 
  

   punctures 
  ; 
  the 
  outer 
  divisions 
  at 
  the 
  apex 
  are 
  obliquely 
  

   truncated. 
  The 
  2 
  — 
  4 
  segments 
  are 
  closely 
  and 
  strongly 
  

   longitudinally 
  striolated, 
  the

  on 
  the 
  second 
  

   being 
  irregular

  the 
  middle 
  and 
  are 
  con- 
  

   tinued 
  to 
  the 
  apex 
  as 
  one 
  ; 
  from 
  the 
  base 
  near 
  the 
  edge 
  

   runs 
  another 
  keel, 
  which 
  runs 
  obliquely 
  to 
  the 
  central 
  

   keel, 
  when 
  it 
  becomes 
  straight 
  ; 
  the 
  sides 
  are 
  distinctly 
  

   margined 
  above 
  ; 
  on 
  the 
  side 
  of 
  the 
  second 
  segment 
  is 
  

   a 
  large 
  smooth, 
  shining 
  space 
  ; 
  and 
  there 
  is 
  a 
  similar 
  

   one, 
  but 
  smaller, 
  on 
  the 
  third 
  in 
  front 
  of 
  the 
  depression 
  ; 
  

   the 
  other 
  segments 
  are
